If I understand that right, it is the following:

1) 1Khz sine wave at -90db.
2) Converted with lame to an mp3.
3) Decoded with lame back to a wav.

Played and it had distortion on the SB3, but not on your PC.

That points to a flaw in your methodology and contradicts your claim:
there was no use of the SB3 firmware for decoding that mp3... you used
LAME.  Yet the SB3 is 'distorted' and the PC isn't?

Perhaps your PC sound card is resampling to 48khz and confusing the
issue.
